CONVEYER OPERATED AT ACCELERATED SPEED.

Applicationled June 1", 1923, Serial No. 645,001, and in France June 17, 1922.

My invention relates to transporting apparatus which servesv to convey from one place to another situated at the same or at different levels, various goods, heavy ob]ects 5 or persons whereby the same shall be caused to travel at increasing or decreasing speeds. For this purpose the said vapparatus comprises various sections disposed in sequence according to the direction of travel of the load distinct rates of speed which increase or ecrease from one element to an-4 other, the speeds of successive sections beingv ythus positively or negatively accelerated. The load is placed, or places itself auto- 15 matically, upon the section having the slowest speed in the case of increasing speeds, and

upon the section having the highest speed in the case of decreasing. speeds. l'

Y f Such apparatus may be combined with end- '120- less platforms which are operated in a conv -tinuous manner and at a uniform speed, and I may be used for access to the saine or as a discharge therefrom, or in other cases as an apparatus for handling goods wherein vari- .25r ious speeds are required to transport the load. The sections operated at increasing speeds and the sections operated at decreasing -1 speeds, the object of my invention, can be constructed in like manner.

Each transporting section of .the series direction of travel of the y load comprises a series of endless funicular elements in parallel disposition which are mounted upon pulleys disposed on two shafts 35 whereof one is a driving shaft and the other serves solely to guide and to support the said elements, the upper part of the said elements these two shafts serving to displace the loads to be when passing upon the driving pulleys, the funieular elements of a. given sectionfare imbricated ...with the-velements of the succeeding section, so that in the whole combination of the said sections the Y situated between support as well as to parts of the elements supporting the loads will form a continuous surface having no projections nor depressions and especially as from one section to the next; this imbricated arrangement of the can be carried out b the use of various forms of construction, an according to one form, the driving shaft of each section serves at the same time as an axle for the supporting and guiding pulleys of the section, the said forni of construction the driving shaft and the supporting shaft of each section are disltinct'from the shafts ofthe adjacent sections and lthe device comprises between the driving shats of two adJacent sections the support- *ing shaft of the section which follows the two sections above mentioned in the direction of travel of the load.

The Asuccessive driving shafts vare actuated at various speeds which increase (or decrease) from one shaft to the next, and the said speeds can be provided for by any suitable means; for example each shaft may be driven by a separate motor 'which is independent of the motors driving the other shafts, and the motors can be provided with speed regulating means controlled by the saine device which serves to change the speed of all the driving shafts at willy and in the same direction, or in other cases all the-driv- 4 ing shafts may be actuated-by afsino'le motor, f

being connected therewith by suita le power transmission means whereby the said shafts may be driven at speeds which increase (or decrease) from one shaft to the next.

The elements of each section may be constituted by belts, chains and the like; the carrying strands of said elements may be supported by frames or like devices which are disposed thereunder or in other cases where chains are used, the links of the chains may have a projecting part whereby each link may p link. which are of a press against the succeeding The appended drawings, diagrammatic nature and are in no wise limitative, relate to an apparatus representing an embodiment of the above-mentioned principles.

Fig. Sis a dia rammatic elevational view of an apparatus wherein each section comprises a driving shaft and a supporting shaft which are distinct from those of the other sections.

The transporting sections a b c d e j' are disposed in sequence in the direction of tnavel stance, comprises a plurality of endless funicular elements ld in parallel position which are disposed upon two sets of pulleys 2d, 3d mounted upon shafts 4d, 4c whereof 4d is the driving shaft and has keyed thereto the set of pulleys 2d actuating the funicular elements of the said transporting section, and'has mounted loose upon the same the set of pulleys 3e supporting .the funicular elements of the succeeding.

transportingsection e, the shaft 4c having lmounted loose thereon the set of pulleys 3d supporting the funicular elements of the same transporting section, and keyed thereto the set of pulleys 2c actuating the funicularclements of the preceding transporting section c; the keyed pulleys 2d of a given transporting section d are in alternate disposition on the driving shaft- 4d with the loose pulleys 3 of the succeeding transporting section, Fig. 3, thus insuring the imbrication of the elements l of a section (l and the elements le of the succeeding section e, the number of pulleys in each of the said sections being equal to number of funi'cular elements inthe corresponding transporting section.

he successive driving shafts 4a, 4", 4d, 4, 4f are actuated at different speeds increasing-or decreasing from one shaft to the next, and herein the device is actuated by the worm wheels 5, 5", 5c, 5, 5, 5f are keyed respectively to the various shafts and respectively engage the Worms 6a, 6b, 6c 6t mounted upon a common shaft 7. The pitch of the said worm gearing (while having thev same direction)`-increases from the first to the last gears, so that a given shaft 4d will rotate at a greater speed than the preceding shaft 4, and at a slower speed than the succeeding shaft 4f; the last shaft of the arrangement rotates at the maximum speed and actuates the elements of the last section at a speed which is equal tothe speed of the main traveling platform alongwhich lthe said apparatus is mounted in order to afford access to the same or discharge therefrom.

'The endless funicular elements 1, 1b, 1 mayconsistof belts, chains or the like; in the case of belts, the pulleys 2a, 2b etc. 3a, 3, etc., are smooth, but where chains are used, the faces of said pulleys are provided with teeth corresponding to the links of the chains employed. The loads are disposed upon the funicular elements of the sections, andthe latter are supported in an suitable manner upon the whole distance tween the fixed and loose pulleys whereon they are mounted, for example by: means of a supporting frame 8, Fig.

of the load. Each section, d, for in.

which and loose pulleys 5, provided with grooves 9 containing the said elements, the lat-ter being made'to project somewhat ahove the said support so that chains for the funicular elements whereof each link l0 has a projection 11 coming into contactA with the adjacent link when the said 4chain is stretched, Fig. 7, the axles 12 of said links being strong enough to support lthe weight of the loads. Irrespectivcly of the form of construction of the funicular elements l, 1h etc., it is observed that the said elements constitute as a -whole a continuous transporting device and that the loads placed upon the said elements will proceed automatically from one section 1" to the next. Slnce any desired number of sections may be employed, my invention provides in a safe and convenient manner for all desired 4variations of speed between the first and last sections'.

In Fig. 8, in each section al, for example, the elements are mounted upon driving pulleys 2d and upon supporting pulleys 8d, but in this case 'the' driving shaft 4d ofthe section d only carries the said driving pulleys, the supporting pulleys 3d being mounted on a shaft 12Fl which is distinct from'the driving various pulleys 2 and 3 may be combined in 4one in order to form a single drum whereon are disposed all the elements of a given section.
